V Machines, of which the following is a specification, reference beingbad to the accompanying drawings, in which-.

Figure 1 is a side view of mymachine. Fig. 2 is a vertical centrallengthwise section of the machine. Fig. 3 is a vertical cross-section ofthe swaging-head on line 3 3 of Fig. 2. Fig. 4 is a verticalcross-section taken through the line 4 4 of Fig. 2. Fig. 5 isanelevation partly in section and shows the stop-motion. Fig. 6 is aview, partly in cross-section, of the casting B and the fingers I). Fig.7 is a top plan view of the machine. Fig. 8 is a plan view of spoke-wireWV, showingblanks and swaged portion. Fig. 9 shows cross-section of therollerbushing 12 Fig. 10 shows roller b Like letters refer to like partsthroughout the several views.

In the drawings illustrating the principle of my invention and the bestmode now known to me of applyingthat principle (see Figs. 1 and 2) thestandardj A supports the casting B, which is the outer casing of theswaging device and is firmlyheld to LhesupportA by the cap A and thebolts a a and nuts a a or in any other suitable manner. 5 The standardsand frame A support the working parts of the feeding and shearingdevices described below. I l 1 G is a driving-pulley splinedat g on thehub g of the fly-wheel G, and" G is a loose pulley on the same hub g.The fly-wheel G, through its hub g, is fast on head-shaft H, through thecenter of which and for its entire length is drilled a wire-passage h ofsuitable diameter to allow the passage of the wire to be operated-upon.The inner end of the wire-passage h is preferably contracted to thediameter of the wire W in order to guide it properly to the swaging-diesJ B is a steel band shrunk on the inner end of easing B over the fingersb to increase the resistance of fingers b to the force of the hammeringand swaging blows and to reinforce the blocks 1).

The stationary headorcasing'B, contain- (See Fig. 3.) Head-shaft H (seeFig. 2) projects into said chamber b and is provided at its inner endwith a boss h, grooved at 77. across its inner face, the opposite sidesof the groove being equidistant from the mid- ,dle of theboss h andcoincident with the lengthwise axis of head-shaft H. The boss 72. {isrecesseduat the middle of its front face to receive the bushing 75*,which is set loosely in. an annular opening therein provided. Thehammers J, the wedges J and the swag'ingdies J 2 are looselyfmounte d ingrooves ii? of the boss h, the hammers J and dies J being actuated bythe successive contact of the camshaped ends j ofthe hammers J .with theinwardly-projectingperipheries of the rollers 6 .The' wedges areactuated by mechanism hereinafter described.

The reinforcing-blocksb, thei'bushing b the rollers 5 the'hamniers J thewedges J, the swaging-dies J {and the head-shaft bushing 71. areallsubject to rapid wear and require to bereplaced with more or lessfrequency. To facilitate the substitution of worn parts, the elements 3ust above mentioned are removable and are retained in theirrespectivepositions by concentricface plates b -and 1),

plate 12 being removablyfixed' to head B and plate I) beingremovablyfixed to the collar or boss h and rotating therewith and having suitableholes orslots b for the'reciprocation therethrough of the wedges-l; Toregulate the force of the eredlbythe hammers J upon-the dies'J I providetapered wedges J inserted between the "hammers J and the dies. J2, pivotally connected with the grooved revoluble collar K, which hasbackward and forward motion upon the collar-stud K, the said stud Kbeing a part of the frame A and operatively conblows delivneeted on theframe with relation to the rotating boss la. The collar K is actuated bythe lever K which is pivotally connected at with the cam-lever K Thecam-lever K is fulcrummed at k on collar-stud K. The cam-lever K isprovided with a cam-roller k which works with the cam K. The wedges Jare forced inwardly between the hammers J and the swaging-dies J by themovement of the collar or wedge-carrier K toward the boss it, thismovement being due to the push of cam K on the cam-roll 70 WVhen theportion 70 of cam K is against the cam-roll 76*, the spring K serves topull the wed ge-carrier K and Wedges J outwardly from their mosteffective wedging position, so that the camshaped ends j of the hammersJ are out of working contact with the rollers 12 One end of spring K isfast to frame A and the other end to cam-lever K and the spring isdistended when the inward movement of the wedge-carrier occurs.

Cam-lever K is provided with a suitable device K (conveniently aturnbuckle) to increase or decrease its length, so that a properadjustment is secured for the insertion or withdrawal of the wedges Jbetween the hammers J and the dies J The cam K and a cam K and aworm-gear K are each supported on shaft K, which is actuated through theworm K (see Fig. 8,) the shaft K, which carries the worm K passingthrough suitable bearings in the frame A and the standard A and beingprovided with suitable drivingpulleys K and K. These pulleys are ofdifferent diameters to secure different speeds for shaft K and are eachmounted on a hub K loose on the shaft K, which is adapted to be coupledto the hub K, which is fast on shaft K Cam-shaft K (see Figs. 2, 4, and5) carries a rocker-arm K, which has a lengthwise slot 70 in which thereis an adjusting-block hf, which is adjusted in its slot by the adjustingscrew L. This block 70 is pivotally connected by a pin Z with aslide-block L, mounted in the lengthwise slot Z of the rocker-lever Lwhich is pivoted at Z to the base of the niachine. The upper end ofrocker-lever L is loosely jointed at Z with the connectingrod L forcarriage D. That end of the rocker-leverL with which the connectingrod Lis thus connected is furnished with a lengthwise opening I, in which aspring Z is mounted rearwardly of the pin Z The other end of theconnecting-rod L is adjustably connected to the carriage by means of theclamp-bolt Z through the elongated slot Z By this adjustment theposition of the carriage in relation to the wire is regulatedindependently of the adjustment of the slidebloek L. an abutment Z whichon the back stroke of the rocker-lever L strikes slide-bar L carrying aninclined shoe Z", which cooperates with the inclined block Z in thevertical Rocker-lever L is provided with slide-bar Z and serves to pullthe slide-bar Z downwardly against the stress of a spring Z mountedabove the horizontal abutment Z through which the slide bar or rod Zpasses, the rod being provided with a fixed collar Z to engage the upperend of the spring I. The upper end of the slide-rod Z extends into thepath of an abutment Z on the bottom of the carriage D. On the backstroke of the carriage the pin Z engages the spring .1 in the outer endof the connecting-rod L and compresses it slightly. As this spring iscompressed the shoe l moves the slide-rod Z downwardly and out of thepath of abutment Z so that the carriage D moves again and carries thewire which has been operated on and is still clamped by the jaws D D (oncarriage D) a distance equal to that portion of the spoke which iscalled the blank. The carriage on its back stroke is first brought torest by engagement of abutment Z with the upper end of the slide-rod l.It is at this time that the wire ceases to move lengthwise and that theswaging-dies J form the shoulder 00, (see Figs. 2 and 8,) theswagiugdies J acting during the interval that the wire is at rest toform anicely-finished shoulder m instead of a more or lessimperfectlyformed shoulder, as would happen if the wire were movedcontinuously. The interval required for compressing the spring 1 andpulling the slide-bar 1 out of the path of abutment Z practicallycorresponds to the interval required to form the shoulder 00, and whenthe shoulder as is completed the carriage moves on to its outermostlimit, the extent of this movement corresponding to the length of theblank.

The jaws D D are loosely pinned at their butt-ends to the upright d ofcarriage D, the free end of one jaw facing the free end of the other jawand both jaws pointing toward the swaging mechanism. The range ofmovement of one of the jaws is limited by a stop 61', mounted in abracket (1 of the carriage D. The other jaw, which is opposite its mate,is moved toward the wire to clamp it by the cam d on the end of rod 61,which carries a roll 61 that runs in the lengthwise raceway d of thevertically-movable frame (1 This frame 61 is guided in vertical ways 01d in the frame A Frame d is provided with a dependent cam-roll (Z whichworks with the cam K When the cam K is in operative position, the frame61 is at its lowest position, fallin g downward in its ways by gravity,and the under jaw D then gravitating away from the wire V. YVhen theswell of thecam K rises against and past cam-roll (Z frame d is lifted,carrying the under jaw D against the wire WV and clamping it against theupper jaw D The dependent cam-roll d is adjustable on the frame (F inorder to suit wires of different diameters, the adj Listing-screw (1'serving, with the adjustable cam-roll (1 to regulate the jaws to wiresof different diameters and also to so adjust the jaws that their workingends are operative on work kept central in relation to the swagingmechanism.

To secure any desired length of blank in a given length of spoke,carriage D is formed with a lengthwise slot d, and the upright d, towhich the jaws D D are pivoted, is provided with a horizontal side plate(Z through which a clamp-bolt d passes into and th rough the slot d.Carriage D is provided with a horizontal slide-plate f, having alengthwise slot f, through which a clampingscrew f 2 extends to lock theplate in adjusted position on the carriage. This plate f carries anuprightf, in which is mounted the wireguide f this guide having a holethrough it for the passage of the wire W One of its functions is that ofashear-blade. The mov-' able member f of the shearing mechanism is avertically-reciprocating bar having a hole through it for passage of thewire, and when the movable member slides upwardly, the wire beingthrough the-hole in guide f and also through hole in member f the wireis cut off, as will be readily uuderst-ood. Outting member f is actuatedby the rocker-leverf, fulcru med on a stud f on the carriage D. One armof the rocker-lever f works in ahole in the movable cutting member ,1,and its outer end is provided with a roller f which runs in the racewayd of the vertically-movable frame (1 The up-and-down motions of thisframe 61 effect the requisite reciprocations of the movable cutting mem:ber f Carriage D is movable lengthwise of th machine toward and awayfrom the swaging mechanism and is mounted on ways (Z in frame AConsidering the mechanism in the position shown in the drawings, itspoke is supposed to have been just severed at the middle of a.blank-section of the wire, the movable cutting memberf is just returnedto its position of rest, and the jaws D D released from the wire, sothat the carriage is free to carry the jaws and the severing mechanismtoward the swaging mechanism, through which it is supposed the second oftwo continuous blanksections has j ust been drawn. These two continuousblank-sections are marked {r and m in Fig. 2. The carriage now movesback toward the swaging-head and the wedges enter inwardly between thehammers and dies to thefull extent provided and. the jaws pass over thewire, which passes outward through the coincident holes in thewire-guide f and the hole in the movable cutting memberf When thecarriage reaches the limit of its inward movement, jaws D D seize at ornearly on the swaged portion of the wire and at the same instant theshearing device is actuated and severs the spoke just pulled through bythe feeding device, and the carriage now moves back with the wire, whichis being constantlyhammered orswaged as it is pulled through the swagingmechanism, until. they abutment Z strikes the stop or slide rod I. Then,as above described, the carriage takes a fresh start rearwardly and theswaging-dies stop work, allowing the formation of two continuous blanks.The jaws are again opened, and the carriage moves inwardly to grasp andpull another spoke.

The main advantages of the herein-described machine are the simplicityof the construction of the swaging-head, permitting quick and easyrenewal of worn parts and the momentary stopping of the carriage whilethe second shoulder is being formed and the subsequent completion of theback stroke of the carriage at the same rate of speed that it had at thefirst part of its rearwardmovement. carriage has been accelerated justbefore the second shoulder was finished, with the result that the wirewas carried too swiftly to perl-Ieretofore the final movement of the mitproper swaging of the spoke about an inch in front of the secondshoulder, this part of the spokes heretofore swaged being characterizedby a rough or ridge-like conformation, deemed highly objectionable bythose skilled in the art.
